Gamma 20-30 nm Alumina Nanopowder Used for Catalyst Carrier
Specification of catalyst carrier used Al2O3 nanopowder:
Phase: gamma
Size: 20-30nm
Purity; 99.99%
Color: white
Nano gamma alumina powder is used as catalyst carrierbecause of its high temperature and corrosion resistance, large specific surface area and high reactivity. The nano alumina powder for catalyst has strong selectivity, small particle size, many pore with wide distribution, pore volume and void distribution.
Gamma Al2O3 nanopowder has a large SSA, high porosity, strong heat resistance and surface acidity, good formability and certain surface alkalinity. It is widely used as a new green chemical material such as catalyst and catalyst carrier.
The actived nano alumina powder exhibits a white fluffy powder state, and the crystal form is gamma.
The particle size is 20-30 nm. The specific surface area is >130 m 2 /g. Narrow particle size distribution, high purity up to 4N, easy dispersion, high specific surface area, high temperature inertness and activity, also called actived alumina.
